Two wires A and B of the same material are of uniform cross-section. Wire A is twice as long B and its diameter is thrice that of B. If the resistance of wire A is 10 ohm, find that of wire B.

Two wires A and B are stretched by the same load. If the area of cross-section of wire 'A' is double that of 'B,' then the stress on 'B' is

Two wires A and B are of the same material. Their lengths are in the ratio 1 : 2 and the diameter are in the ratio 2 : 1. If they are pulled by the same force, then increase in length will be in the ratio

Assertion : Two wires A and B have the same cross-sectional area and are made of the same material but the length of wire A is twice that of B. For a given load, the strain in wire A is twice that in B. Reason : For a given load, the extension in a wire is prportional to its length.

Two pieces of wires A and B of the same material have their lengths in the ratio 2 :3 and diameters in the ratio 2 : 3. They are stretched by forces, which are in the ratio 2 : 3. Their elongations are in the ratio

Two wires are made of the same material and have the same volume. However wire 1 has cross-sectional area A and wire 2 has cross-sectional area 3A. If the length of wire 1 increases by Deltax on applying force F, how much force is needed to stretch wire 2 by the same amount?

Two wires of the same material and same cross section are stretched on a sonometer. One wire is loaded with 1.5 kg and another is loaded with 6 kg. The vibrating length of first wire is 60 cm and its fundamental frequency of vibration is the same as that of the second wire. Calculate vibrating length of the other wire.

Two wires of the same material and the same cross section are stretched on a sonometer in seccuession. Length of one wire is 60 cm and that of the other is 30 cm. An unknown load is applied to the first wire and second wire is loaded with 1.5 kg. if both the wires vibrate with the same fundamental frequencies, calculate the unknown load.

Two wires A and B are made of same material and are having same weights. The strain in A will be more when
